COLLAR-WRAPPING MACHINE.

Specification of Letters Patent.

Patented May f, 19117.

Application filed May 3, 1915. Serial No. 25,610.

To all whom it may concern Be it known that I, PETER Gr. LEI-IMAN, a citizen of the United States, residing at Mishawaka, in the county of St. Joseph and State of Indiana, have invented certain new and useful Improvements in Collar- Wrapping Machines, of which the following is a specification.

The invention relates to a machine designed primarily for the wrapping of collars wherein any predetermined number of collars may be properly applied to the wrapping roller and interwrapped and enveloped in a suitable wrapping of paper or other material to provide a compact bundle or package, wherein the collars are held in a uniformly curved position to maintain their correct shape and prevent possibility of breaking while in the package.

The present improvement is designed particularly to provide for the expeditious handling of collars and material, the automatic severing of the material when the predetermined quantity has been used and the simple and expeditious removal of the wrapped collars as a package from the machine, all parts being readily accessible for adjustment, removal orrepair when desired.

Figure 1 is a front elevation partly broken out, of the improved machine.

Fig. 2 is a side elevation of the same, the Wrapping roller being shown in package removing position in dotted outline.

Fig. 3 is a plan of the machine.

Fig. 4 is a broken perspective showing the automatically adjustable cutter.

Fig. 5 is a perspective view of the wrapping roller.

In the accompanying drawings wherein is shown the preferred embodiment of detail, the improved machine comprisesa base 1 of suitable form'to properly support the device, from which, near one edge, rises an upright 2, preferably in the form of a comparatively narrow and thin strap. Secured to the upright, near the upper end and projecting laterally therefrom, is a shaft 3 on which through the medium of the usual cone-supports 4:, is designed to be arranged a roller 5 of paper or other suitable material, the material being of suflicie'ntwidth for the purpose desired.

Slidably mounted upon the upright 2 is a cutter frame involving a slide element 6 having flanged or under-cut side walls to slidably embrace the edges of the upright 2,

whereby the slide has free telescopic movement with relation to the upright. Projecting laterally from the upper end of the slide frame is a cutter 7, comprising a comparatively narrow blade-like element, the forward or cutting edge 8 of which slightly V-shaped in planand appropriately sharpened. As thus arranged it will be obvious that through the telescopic or sliding arrangement of the knife frame with the upright the knife will rest upon the surface of the roll of wrapping material at all times, automatically accommodating itself to the diminution of the roll as the material is used. To one side edge of the knife frame, as at 9, is secured an arm 10, on the upper or free endof which is provided a sleeve-like bearing 11. ltotatably mounted in the bearing 11 is a shaft projection 12 forming a fixed part of what 1 term a wrapping roll 13. The shaft projection 12 of the roll is slightly greater in length than that of the bearing 11 and its outer end is of angular form in cross-section as at 14, to receive an appropriate opening in a crank operating handle 15, whereby the roll is rotatable when desired.

The roll proper comprises a hollow cylindrical body 16 formed immediately adjacent the shaft projection 12 with an annular roughened or knurled bearing surface 17. The roller is formed with a longitudinally extending slot 18 opening through the edge thereof remote from the surface 17, and

extending approximately to said surface as clearlyapparent from Fig. 5. The hearing 11 is of such length that when the roll is in position therein the roughened surface 17 will bear upon the paper or other wrapping material adjacent the edge thereof, as clearly shown in Fig. 1, the saidroughened surface serving as a feed element to feed the paper from the paper roll as the folding roll is rotated. Secured to the sliding frame adjacent one edge thereof and preferably on the inner side is a paper or other material guide 19 comprising preferably a strip of wire or the like secured to the frame, projecting laterally across in front of the paper roll and terminally extended upward in a curved finger as at 20, which latter is positioned about mid-width the paper roll and is curved into close proximity to and concentric with the surface of the wrapping roll. The wrapping roll is preferably slightly conical in shape, that is the free end thereof is of slightly less diameter than the end carrying the roughened surface 17, for a purpose which will presently appear, and the arm 10 is also of a length to permit the Wrapping roll to rest by gravity immediately above the material of the paper roll on the side opposite the sliding frame to that on which the arm 10 is pivotally mounted, this disposition permitting the arm 10 to be turned upwardly toward the rear so as to move the wrapping roll a considerable distance from the proximate surface of the wrapping material or paper roll, as shown in dotted lines in Fig. 2.

In use, the collars to be wrapped are grouped together and their tabs at one end of the collars placed slightly within the slot or channel 18. The crank handle 15 is now rotated and the roughened surface 17 of the wrapping roll causes the paper, directed by the guide 19, to be fed up wardly around the wrapping roll, the end of the paper being held down by the operator until the same is gripped by the winding of the collars and paper about the roll. The rotation of the wrapping roll rotates the collars about said roll and at the same time feeds the paper or other wrapping material between the respective rolls of the collars and around the same. After a sufficient number of enveloping folds have been made, the wrapping roll as a whole is swung upwardly on the pivotal connection of the arm 10, which action causes the knife 7 to sever the paper, the V'shaped formation of the knife presenting a piercing point which initially pierces the paper, at about centrally of its width so that further upward movement of the paper causes the knife to readily sever the same throughout its width. As the wrapping roll is of less length than the width of the paper it is obvious that there is presented innnediately succeeding the operation described, a free portion of paper beyond the free edge of the wrapping roll, which may be turned inwardly to seal the end of the package. The package and collars thus wrapped may be readily withdrawn from the wrapping roll as the latter is slightly cone-shaped, after which the supports or relatively inner end of the package may be turned in to seal the same.

As presented the improved machine will readily wrap any number of collars, maintaining them in regular, even, rounded folds, and permit the ready sealing or closing of the package in the manner described. As the entire operative parts of the mechanism,

that is the wrapping roll, guide and cutter,

will be at all times maintained, whereby the complete effectiveness of the device is insured.

What is claimed is:

1. A collar wrapping machine including a mounting for a paper roll, and a wrapping roll mounted for downward movement by gravity having operative contact with;

and supported against downward movement by the paper roll, whereby the wrapping roll will automatically adjust itself for operative relation with the paper roll as the latter is reduced in size by the use thereof.
